This video shows you how to use the new Touch sensor module on ESP32 Lua (NodeMCU). The library lets you access the touch hardware built into the ESP32 which lets you use up to 10 touch sensor pads. This lets you create touch buttons using normal conductive substrates like PCBs, copper tape, silver ink, or other conductive surfaces.
